摘要：The article presents an analysis of modern geotechnological methods of gas extraction from coal technogenic deposits. Special attention was focused to surface methods complex resource development, which concentrated in filled rock dumps and sludge accumulators of coal-processing factories. The work describes physical-and-chemical methods of thermal impact on solid carbon-contained raw materials, which is considered as a binary mixture of coal and rock, in an oxygen-free medium or with the use of oxidants. The article presented the researches results of catalytic transformations taking place in the structure of a coal substance. Various versions of the use of catalysts in the processes of physical and chemical transformations of coal were proposed. The conducted researches allow to analyze the existing methods of impact on the mine medium identify the most perspective directions for the development of new methods in the field of geotechnological processes of gas extraction from coal technogenic deposits.
